Resource discovery is a real challenge in grid systems due to the dynamicity of nodes (i.e. any node can join or leave the system at any moment). This paper proposes a new protocol for resource discovery in dynamic grid systems. The hypothesis is that a grid is composed from a

WSNs are playing a crucial role in real world applications. Due to the features of the resource-constrained and battery-aware sensors; in WSNs energy utilization has found to be a major interesting subject of research. WSNs compose battery-powered nodes which are connected with the base station to for certain action or

In this paper, based upon the concept of improving the novel congestion control scheme in Wireless Sensor Network (WSN). In WSN congestion is an important issue. Congestion occurs at the transport layer of the OSI model. The novel congestion control scheme proposed a rate-based Fairness-Aware Congestion Control protocol (FACC), which

In the present scenario, cellular service provider facing bandwidth shortage in conventional cellular system, and delivering high quality, low latency video and multimedia applications using 3G system which is on ground. The 4th generation cellular networks are expected to be implemented in next few years. Here, the authors present the

Mobile Ad hoc NETwork, abbreviated as MANET, is flexible, self-configuring, wireless ad-hoc network. MANET do not require pre-existing or pre-defined infrastructure, instead it configures and creates a network dynamically. All available nodes (devices) in MANET act as routers and are allowed to move freely in any direction, even in and
...

In the present scenario various wired and wireless networks are contributing in information access for different users. But as the authors are moving towards next generation, the communication is targeting for integration of these wired and wireless networks. Once a client obtains a global address from internet gateway it is

Mobile computing facilitates users to keep the information handy and also continuous access to the application by using mobile computing devices (i.e. Smartphone, palmtop, laptop and tablets) without using wired network. It provides flexible communication to network users; they can access network applications anytime and anywhere. Communication between these devices

Intrusion Detection System (IDS) is one of the emerging techniques for information security. Security mechanisms for an information system should be designed to prevent unauthorized access of system resources and data. Many intelligent learning techniques of machine learning are applied to the large volumes of data for the construction of

The wireless LAN standards IEEE 802.11 (a/b/g) provides multi-rates capabilities. To achieve high network performance, devices need to adapt their transmission rate dynamically under varying conditions. Rate adaption algorithm is a critical component of their performance, only very a few algorithms have been published and the differences between their mechanisms
